I recently had an issue with my Mac Mini (mid 2010), it has been upgraded 2 times to Mountain Lion, and I am trying to install OS 10.8.2 back on the mini but with a new blank drive. Has this utility worked for anyone? BTW please relate your experiences trying to restore the latest version of OS X to a new drive.


This would help me out a huge amount as I have wasted enough time listening to the "Experts".

    You should be able to use use OS X Internet Recovery as long as you upgraded your mid-2010 Mini's firmware. I have done it and can confirm that it works, even with a new, empty, unformatted hard disk.


    If for some reason it does not work for you, it will be unproductive to determine the reason for now. In that case you must boot from another device, use Disk Utility to format it, and subsequently install a version of OS X. You can reinstall Mountain Lion by downloading it again from the Mac App Store. It will appear under the "purchases" tab.


    The usual way of doing this is to boot from your original grey System Restore DVD (hold the c key while you start your Mini). If you have an external drive containing a bootable OS X volume you can boot using Startup Manager (hold an Option key while you start your Mini). If you have a Time Machine backup, you can boot from it, which will load OS X Recovery and allow you to restore from your Time Machine backup.

    Yes, I have used a USB thumb drive created from the OS X Recovery Disk Assistant to reinstall Mountain Lion to my rMBP and a Mac Mini mid-2011. The DIsk Assistant basically just puts the Recovery HD of your OS X install on a USB thumb drive. No installer just the OS X Utilities menu and the option to Reinstall OS X as a option just like the Recovery HD on your hard drive. I have also used it to install ML to a new SSD drive in my Mac Mini.

    Have you stayed there while the restore is happening and clicked your mouse while it's running? It should continue processing while your screen is black and either a keyboard key press or a mouse click brings your screen back. It's always worked for me.

    The d/l of Mountain Lion is over 3 GBs. You might expect about 45 minutes at typical advertised cable speeds of 10 -15 mbs. Not sure how large your Windoz d/ls were?
